Thank you for the updates DR0ID,

I have run your pygame-alternate2.py: 39.6% CPU on Mac OS X, up to 42%
CPU during full screen scrolling.

I notice the spikes in CPU in the rabbyt version as well both on Linux
(Pentium M / Intel GPU) and Mac (PPC G4 / ATI GPU) both systems spend
the majority of the time around the 6%-7% CPU mark and usually during
the full screen scroll I see a spike upwards towards 18% CPU for what
seems to last less than a second then immediately drops back down to
6%-7% CPU range. I can only guess that it might be related to
loading/addressing of textures.

Animations under Ubuntu 7.10 Gutsy Gibbon running on Dell Latitude D510 hardware

Gnome 2.20.1

With pyglet a good trick is $python -m pyglet.info which will dump
information on your system including the detected/reported OpenGL
system (what it supports/extensions). It might be useful for
comparison purposes:

If there are any Pygame diagnostic utilities you want me to run let me know.
